When a living body absorbs radiation, the radiation can cause shemical changes in the body. Some of these Might effect the DNA and cause a rapid, out of control growth of cells...CANCER.
Radioactivity affect the water molecules. Radioactivity makes it harmful
The protective apron used by dentists contains lead, which is highly opaque to radioactivity. (You would also notice that if you read Superman comic books; lead is used to safely contain kryptonite.)
True. Radioactive materials can be found in varying amounts in soil, water, air, and even in our bodies. However, the levels of radioactivity in the environment are usually very low and not considered harmful to humans.
radioactivity basically related to the decay of nucleus of atoms during this process many harmful rays emit which causes the skin diseases.

It's not technically baldness, I suppose "hair loss" is more accurate. But, yes, radioactivity is physically harmful and loss of hair is a common result from heavy exposure. We're talking nuclear reactor or chemo-therapy with radioactive materials levels, not "stand in front of the microwave" or "get sunburnt" levels...
Radioactivity is dangerous because it emits high-energy radiation that can damage cells and DNA in living organisms. Exposure to radioactivity can lead to health risks such as cancer, genetic mutations, and radiation sickness. Long-term exposure can increase the risk of developing various diseases and can have harmful effects on the environment. It is important to limit exposure to radioactivity and take precautions to protect against its harmful effects.
The process by which materials give off energy from a uranium atom was named radioactivity by Marie Curie in the early 20th century. She discovered that certain elements, like uranium, emit radiation spontaneously.
The harmful effects of materials that are invented by technology are materials that are not biodegradable. This is because the materials are synthetic materials and cause destruction to the environment.
Nobelium is a highly radioactive and synthetic element with no known biological role. Due to its short half-life and high radioactivity, it is considered harmful to living organisms and the environment.
Natural Radioactivity arises from radioactive components contained in nature. Artificial Radioactivity will come through element produced with in nuclear reactors as well as accelerators. Natural Radioactivity is a spontaneous process of disintegration. Artificial Radioactivity is carried in synthetically produced radioactive elements used in nuclear reactors.
Radioactivity gradually falls in all radioactive materials, how quickly it falls depends on the half-life of the material. The radioactivity of a material with a short half-life will fall alot quicker than the radioactivity of a material with a long half-life.
